Frequency-aware reconstruction of forwarding tables in name-based routing

Abstract

In the future Internet, routing on contents or resources is anticipated as the post-Internet Protocol (IP) routing. The final goal of our research is to realize routing based on the name of a resource in the network layer. Towards this purpose, we use the 'name' for routing, particularly the 'fully qualified domain name (FQDN)' to show the feasibility of name-based routing and to generalize it to resource-based routing. When writing the routing information of hierarchically structured FQDN into a hierarchical virtual topology, mismatch between the virtual topology and physical topology can occur if the virtual topology lacks the physical topology's information. In addition, routing tables should be reorganized to reflect the different access frequency among the FQDNs. In this paper, we propose an algorithm for reconstructing routing tables to better map a virtual topology to the physical topology. As a result, we show that using the access frequency and physical topology's information increases the efficiency for searching FQDN.
